Papervision Particles
A few weeks ago I started teaching basic papervision in my 4th semester Flash class (Digital Media Arts program @ Seneca College). So far we have covered basic class imports, setting up the scenes, viewports, render engines, and adding basic prims. However, students are always impatient to get to the fun stuff! So I decided to start taking a look at basic materials and shaders (Andy Zupko has a really good shader tutorial to get you started).
Getting a basic particle field to work in pv3 is dead simple. I did a bit of digging through the class structure and came across ParticleField.as. We start with the following two imports:
import org.papervision3d.materials.special.ParticleMaterial; import org.papervision3d.objects.special.ParticleField;
We will then create a basic function to build our particle field:
private function createParticles():void
{
//Create a new particle material;var pm:ParticleMaterial = new ParticleMaterial(0xFFFFFF,1);
//Create a new particlefield.
var particleField:ParticleField = new ParticleField(pm, 2000, 5000, 5000, 5000);
scene.addChild(particleField);
}
Pretty easy eh!
Thanks for that very simple and straight forward code sample, ParticleField was just what I was looking for and didn’t know existed.
No problem…You can find lots more stuff here http://www.pv3world.com
No matter what I do particles DO NOT work in papervision, I get other stuff to work. what the hell is the problem. All classes set up fine (I think), I have the newest build. Is thier something special about the particle class that doesn’t publish in flash cs3. this is getting frustrating.
I have downloaded the source code, and created a data class called particle.
After that I opened Flash CS3 to add the class particles.as in the Document class area, but no particles. I don’t see particles appear.
This is an old post with old information, I highly doubt any of it works anymore. Plus, I don’t do flash these days, very out of the loop. Sorry, good luck!
